Francis L. Wellman, The Art of Cross-Examination — Chapter 6 (1903)
“ Some witnesses, under this style of examination, lose their tempers completely, and if the examiner only keeps his own and puts his questions rapidly enough, he will be sure to lead the witness into such a web of contradictions as entirely to discredit him with any fair-minded jury. A witness, in anger, often forgets himself and speaks the truth. His passion benumbs his power to deceive. Still another sort of witness displays his temper on such occasions by becoming sullen; he begins by giving evasive answers, and ends by refusing to answer at all. ”
